Abstract

A tool for installing a helical coil insert in a tapped hole formed in a workpiece includes a tubular body having a bore extending along its axis, a mandrel coaxially disposed in the bore of the tubular body, a punch coaxially disposed in a bore of the mandrel, a motor for rotating the mandrel, and an air cylinder for applying an axial force to the punch. The tubular body includes a recess at one end for carrying a helical coil insert in alignment with the bore. An opening in the tubular body allows a user access to the recess. The mandrel is movable from a position retracted from the helical coil insert, to a position engaging the helical coil insert, and to a position installing the helical coil insert a selected depth in the tapped hole of the workpiece. The punch slides axially in the bore of the mandrel to remove the tang from the helical coil insert upon installation of the helical coil insert in the tapped hole.
